The Industry responsible for the discovery and development of crop protection compounds has undergone dramatic changes and increasing consolidation since the initial innovations in synthetic organic fungicides, herbicides and insecticides in the late 1940s and early 1950s. Likewise, there have been striking changes in the rate of introduction of new crop protection compounds over the past 70 years. While numerous studies over the past five decades have signaled the ongoing decline in the numbers of new active ingredients (AIs), a detailed analysis of the trends in the rate of introduction of crop protection compounds shows a more complex pattern in the overall output of new AIs. The recent (post‐2000) decline in the numbers of new herbicides is the primary source of the perceived decline in overall numbers. When herbicides are excluded, the output of new fungicides and insecticides has been relatively constant, especially for the past 20 years. A notable observation is that innovation, as measured by the number of compounds representing a new chemical class (First‐in‐Class) has been relatively constant for the past 70 years, and most recently has been driven by the appearance of new fungicides and insecticides. Thus, the discovery and development of new AIs for crop protection and public health continues, in spite of the many challenges and changes to the Industry. © 2021 Society of Chemical Industry
